Did your relationship change after having your first baby?

Currently 8 months pregnant and I’m just so heartbroken at the thought of how much my relationship had changed. My bf used to be so sweet, sometimes I would even be embarrassed of how corny he was with his gifts and PDA, but all if that has completely changed since I got pregnant. I can’t remember the last time he genuinely hugged me, caressed me, kissed me, held my hand, took me out, nothing I’ve got nothing from him .... and I’ve told him how I felt (maybe it was my fault for texting him rather than talking to him but he had gone to his moms that day) but he never replied to me.. he says he still loves me but it takes for me to ask him. Maybe I’m overly emotional but things were never like this and I need him now more than ever.

Is this normal? Is it part of pregnancy? Having your first child? Will it get better?
